The study will be conducted as a multi-center, randomized, double-blinded, placebo controlled, crossover design. The investigational drug (vardenafil ODT (Orally Disintegrating Tablet)/placebo) will be given as a single administration at a dose of 10 mg vardenafil ODT during Period 1 or 2; the blinded matching placebo will be given as a single administration during the opposing period. The random code will determine the order of active drug (vardenafil ODT) and placebo for each subject. Blood pressure and heart rate profiles will be recorded by automated device pre-dose for 8 hours post-dose during Periods 1 and 2. The non investigational drug product (vasodilator), Procardia XL, will be background treatment for hypertension, taken daily by each subject. All subjects must be stable on the vasodilator for at least 4 weeks prior to Day 1 of Period 1. Special conditions for this study include the requirement that all subjects will be male, are between the ages of 65 and 80 years, and will have a diagnosis of erectile dysfunction (ED), as well as hypertension. Planned sample size will be 40 subjects evaluable for the primary analysis. Of the 40 subjects valid for this analysis, 20 will be between the ages of 65 and 69 years, and 20 subjects will be between the ages of 70 and 80 years. The total duration of the study will be approximately one year from first subject treated to last subject treated, including replacement of any subjects who fail to complete both periods of crossover dosing.

Criteria

Inclusion Criteria:

Subjects must fulfill all of the following criteria before being included in the treatment period i.e., before receiving any dose of the study related medication (Sponsor supplied Procardia XL, or vardenafil Orally Disintegrating Tablet (ODT) /placebo tablets):

Diagnosis of both essential hypertension (HTN) and erectile dysfunction (ED)

High blood pressure, or hypertension, is defined in an adult as a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. As stated in the current American Heart Association guidelines.

Documented ED for more than 6 months according to the National Institutes of Health (NIH) Consensus statement (the inability to achieve or maintain penile erection sufficient for satisfactory sexual performance). The diagnosis for ED will be confirmed using the five-item version (Rosen RC) of the International Index of Erectile Function (IIEF-5), see Appendix 14.4. The total IIEF-5 score must be at least 8, and not exceed 19. Subjects must have used at least one Phosphodiesterase-5 (PDE-5) inhibitor, such as Viagra, Levitra or Cialis at some time prior to entry in this study.

Age: 65 to 80 years (inclusive) at the first screening examination / visit

Body mass index (BMI): above/equal 18 and below/equal 32 kg / m²

Exclusion Criteria:

Subjects are to be excluded from the study if they display any of the following criteria:

Medical and surgical history

Pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal. This includes severe renal impairment (on dialysis or not) and moderate or severe hepatic disease.

Known hypersensitivity to calcium channel blockers (active substances or excipients of the tablet preparations)

Known hypersensitivity to PDE-5 inhibitors, such as Viagra, Levitra or Cialis (active substances or in some instances, excipients of the tablet preparations should be considered as possible allergens, e.g., lactose, aspartame)
